Domes Noruz Kassandra, Halkidiki

The hotel's own tagline, "a beach club with rooms," is doing a lot of honest work. This adults-only resort on the Kassandra peninsula in Halkidiki divides its pools between "Vibrant" and "Secret," and the atmosphere at each earns the label. Rooms run in white and cream with the kind of high-end fittings that justify a long afternoon indoors. The Soma Spa leans more social than serene, and Topos handles seafood-focused Greek cooking when the beach eventually releases you.
